Improved casing for water-wheels



UNITED STATES PATENT OEEIGE.

JAMES D. BRYSON, OF NEWCASTLE, PENNSYLVANIA.

IMPROVED CASING FOR WATER-WHEELS.

Specification forming part of Letters Patent N0. 82,486, dated September 29, 1868.

To all 'whom it may concern Beit known that I, JAuEs D. BRYsoN, of Newcastle, in the county oi' Lawrence and State of Pennsylvania, have invented a new and Improved Casing for Water-Wheels; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, makinga part of this specitication, in which- Figure 1 is a vertical section through the line mx of Fig. 2. Fig. 2 is a horizontal section through the line a' a' of Fig. 1. Fig. 3 represents different horizontal sections of a bucket, taken at different points from top to bottom.

This invention consists of a casing for water-wheels made up of a curb having a number of apertures for the passage of water, and provided at its lower edge with an external circular tiange, and also provided with a certain number of guides tangential to the inner surface ot' said curb, which guides pass through the aforesaid apertures, and serve to facilitate the ow of water into the curb, and also to support a horizontal ring upon their upper edges, said ring being concentric with the curb, between which and the rin g is passed a circular gate, which may receive a rotary mot-ion sufficient to cause it to open and close the aforesaid apertures in the curb, and also the vertical mot-ion necessary to its adjustment in or removal from its place between the beforeanentioned ring and curb.

In the drawings, A A represent the curb, having' apertures a a, for the passage of water and the insertion ofthe guides C. B is a iiange that projects outward from the lower part ofthe curb. C C are vertical metallic plates bolted at their outer edges to the outer edges of the flange B and the ring B', which latter rests upon the Lipper edges of the said plates, and is concentric with the curb A. there being a space between the said curb and ring wide enough to permit the circular gate D to be dropped in between them.

The gate D slides around the curb and shuts against the vertical walls of the plate C near their centers, the said plate extending through the walls of the ring by means ofthe apertures a. The plates'C may be removed from the curb upon detaching the bolts which fasten them thereto.

E represents a water-wheel, which, though forming no part of my invention, I will briey describe. It has side brackets e e, the lower portions of which discharge water at the bottom of the curb by lateral action, and the upper portions of which are provided with curved passages e', through which a portion ot' the water escapes to the center of the wheel, where it is discharged on thecircular-vcnt principle.

The buckets e aremade wide and shallow at their tops and narrow and deep at their lower ends. Grosssections ot' them at any point below the center vent-oriiioe would he represented by the lineszz, Fig. 3. The edges of the buckets are curved, as shown at m m, Fig. l, and the whole bucket pai-takes ot' the general nature of that'curve. Such part of the water as cannot escape through the side vents passes onc to the center through the orifice c'.

Having thus described my invention, what I claim as new, and desire to secure by Letters- Patent, is-

A casing for water-wheels consisting of the curb A, the iange B, the ring B', supported upon the guideplates C, and the gate D, all constructed and arranged to operate substantially as described. 'f

To the above specification of my improvement I have signed my' hand this 15th day of February, 1868.

JAS. D. BRYSON.
